Been using PolarFinder Pro for a couple months now. It’s basically an app that helps you precisely position your telescope mount, which is super useful for astrophotographers. You can choose to use your GPS or enter custom coordinates and times to figure out the exact position of Polaris (north) or Sigma Octantis (south). Once you’ve got the position calculated, the app shows you how to align your polar scope – it even has an option to flip the image so it matches what you see through the eyepiece. Pretty nifty stuff if you’re into that kind of thing.
